Description
Verwendung von roten Phosphor enthal.tenden Polymeren zur Der stellung von flammwidrigen Fäden und Fasern === === == === = = = = = = == = = = = - = -= == == - - = Die Erfindung betrifft die Verwendung von aus der Schmelze verformbaren Polymeren zur Herstellung von flammwidrigen oder selUstverlöschenden Fäden und Fasern.Use of red phosphorus containing polymers for the position of flame retardant threads and fibers === === == === = = = = = = == = = = = - = - = == == - - = The invention relates to the use of deformable from the melt Polymers for the production of flame-retardant or self-extinguishing threads and fibers.
Es ist bekannt, daß der Zusatz von rotem Phosphor bei Gießharzen wie auch bei Thermoplasten und geschäumten Kunststoffen zu einem wirksamen Brandschutz führt (BE-PS 715 11o, BE-PS 752 166; US-PS 3 373 135, GB-PS 1 112 139, GB-PS 1 147 009, GB-PS 1 157 419; DAS 1 173 641; DOS 1 965 635, DOS 1 944 o56, DOS 1 812 512).It is known that the addition of red phosphorus in casting resins such as effective fire protection even with thermoplastics and foamed plastics leads (BE-PS 715 11o, BE-PS 752 166; US-PS 3,373,135, GB-PS 1,112,139, GB-PS 1,147 009, GB-PS 1,157,419; DAS 1,173,641; DOS 1 965 635, DOS 1 944 56, DOS 1 812 512).
Es ist ferner bekannt, zellulosehaltige Formprodukte mit verminderter Entflammbarkeit, insbesondere Fäden, Fasern, Garne, Filme und Faserbahnen herzustellen, die 1 - 25 Gewichtsprozent, bezogen auf den Zellulosegehalt, roten Phosphor enthalten (DOS 1 944 o56).It is also known cellulosic molded products with reduced Flammability, in particular to produce threads, fibers, yarns, films and fiber webs, which contain 1 - 25 percent by weight, based on the cellulose content, of red phosphorus (DOS 1 944 056).
Aufgabe der vorliegenden Erfindung ist es, flammwidrige Fäden und Fasern aus schmelzspinnbaren Polymeren herzustellen.The object of the present invention is to provide flame-retardant threads and Manufacture fibers from melt-spinnable polymers.
Diese Aufgabe wurde dadurch gelöst, daß aus der Schmelze verformbare Polymere, denen roter Phosphor während der Polymerenherstellung zugesetzt worden ist, zur Herstellung von Fäden und Fasern verwendet werden.This object was achieved in that deformable from the melt Polymers to which red phosphorus has been added during polymer manufacture is used to make threads and fibers.
Der rote phosphor ist in Form von Partikeln, deren mittlere Korn-Größe kleiner oder gleich lo /u (im Durchmesser) ist, vorzugs weise aler im Bereich von 1 lAi.s 3 /u liegt, zugesetzt worden.The red phosphorus is in the form of particles, their mean grain size is less than or equal to lo / u (in diameter), preferably aler in the range of 1 lAi.s 3 / u has been added.
Die Konzentration an rotem Phosphor in dem erfindungsgemäß verwendeten aus der Schmelze verformbaren Polymeren beträgt zweckmäßig je nach Flammschutzeriordernis zwischen o,5 und lo Gewichtsprozent, vorzugsweise zwischen 1 und 5 Gewichtsprozent, bezogen auf das Gewicht des Polymeren.The concentration of red phosphorus in the one used in the invention Polymers deformable from the melt is expediently depending on the flame protection requirements between 0.5 and 10 percent by weight, preferably between 1 and 5 percent by weight, based on the weight of the polymer.
Es ist für Polyester vorgeschlagen worden, den feingepulverten roten Phosphor mit der Diolkomponente anzuteigen, und diese Aufschlämmung unter weitgehender Ausschaltung der Entzündungsgefahr dem unter Stickstoffatmosphäre stehenden Reaktionsschutz zuzufügen.It has been suggested for polyester, the finely powdered red Acute phosphorus with the diol component, and this slurry under more extensive Elimination of the risk of ignition of the reaction protection under a nitrogen atmosphere to add.
Entsprechend kann der rote Phosphor auch den anderen Ausgangsmonomeren bei der Polymerherstellung zugefügt worden sein. Uberraschenderweise lassen sich die so hergestellten Polymeren einwandfrei aus der Schmelze verspinnen und ohne Schwierigkeiten zu Fäden und Fasern mit hoher Festigkeit verstrecken.The red phosphorus can also correspond to the other starting monomers have been added during polymer production. Surprisingly, can The polymers produced in this way are perfectly spun from the melt and without Difficulty drawing threads and fibers with high strength.
Die Wahl des roten Phosphors als beizumischendes Flammschutzmittel hat den Vorteil, daß bei der Verbrennung der Fäden und Fasern der gesamte Phosphor in der Asche verbleibt und nicht in flüchtiger Form entweicht, wie bei den halogenhaltigen Flammschutzmitteln, wo schädliches Argas - Halogenwasserstoff - entsteht.The choice of red phosphorus as the flame retardant to be mixed in has the advantage that when the threads and fibers are burned, all of the phosphorus Remains in the ashes and does not escape in volatile form, as with the halogen-containing ones Flame retardants where harmful argas - hydrogen halide - is produced.
Die erfindungsgemäß verwendeten Polymeren weisen die für das Schmelzspinnen üblichen Viskositäten auf.The polymers used in the present invention have those for melt spinning usual viscosities.
Neben dem roten Phosphor könnten die Polymere auc die üblichen Zusätze wie Mattierungsmittel, Pigmente usw. enthalten.In addition to the red phosphorus, the polymers could also contain the usual additives such as matting agents, pigments, etc.
Als lineare schmelzspinnbare Polymere können Polyester oder Polyamide eingesetzt werden, z.B. Polyester der Terephthalsäure mit Diolen mit 2 - lo Kohlenstoffatomen im Molekül und die bekannten Mischpolyester sowie als Polyamide Poly- -caprolactam und Polyhexamethylenadipamid. Bevorzugt ist Polyäthylenterephthalat.Polyesters or polyamides can be used as linear melt-spinnable polymers can be used, e.g. polyesters of terephthalic acid with diols with 2 - 10 carbon atoms in the molecule and the well-known mixed polyesters and as polyamides poly- caprolactam and polyhexamethylene adipamide. Polyethylene terephthalate is preferred.

Besonders bemerkenswert ist es, daß trotz des Gehalts an rotem Phosphor hochfeste Fäden -erhalten werden, die z.B. für technische Artikel eingesetzt werden können, insbesondere für beschichtete Gewebe.It is particularly noteworthy that, despite the red phosphorus content high-strength threads can be obtained, which are used e.g. for technical articles can, especially for coated fabrics.
